Hey guys. I need to make treat pouches for animal training. So I need a fabric that's waterproof, or at least water resistant. What kind of fabrics would that be? (Scotchguarding would be unsuitable, I'd think as the pouches would need to be washed and I don't know if it's toxic.)

A lot of treat pouches use them so that they can be propped open or closed semi-securely to keep out nosey animals. I'd like to use them in mine too. But I can't find a supplier until I know what they're called.

The hinges are sometimes called squeeze frames or snap frames...look for them from purse making supplies.

As for the fabric. I've made some treat bags for my dogs out of packcloth and then lined with nylon ripstop with a polyurethane or silicone coating. The coating makes it waterproof and the nylon is a smooth fine weave that wipes clean easily, which is nice for moist treats like bits of hot dog and cheese. The packcloth is heavier so makes a nice pouch that holds it shape well and is really durable. Both can be bought for outdoor fabric stores...I've bought from http://www.seattlefabrics.com/nylons.html#silicone%20ctd%20rs and http://www.rockywoods.com/Fabrics-Kits/All-Ripstop-Nylon-Fabrics. I've seen these fabrics at box stores (like Joanns) at times but don't know if most stores keep them in stock.

You could use PUL as it's waterproof but the front side is a cotton knit which is soft and textured...great for soft clothing like baby diapers but it will absorb moisture and smells as well as collect dirt and hair. Also you still have to line it with something as the polyurethane coating will rub off if left exposed. It's also a knit so doesn't hold it shape as well. It's doable but wouldn't be my 1st choice.
